总结的激活和octavolateralis传出系统的行动进行了研究，从假定的传出和单一的初级传入神经元在警觉，自由游泳蟾蜍慢性记录的放电模式。在前侧线神经中分离的传出轴突在施加到头部或躯干的触摸刺激后显示出阶段性放电，并表现出对视觉刺激的持续放电。初级传入神经的静息放电模式分为不规则、爆发式、规则和沉默类。传入放电经常受到呼吸运动期间产生的头部周围低频（< 1 Hz）水运动的调制。当鱼与记录电极植入侧线神经视觉刺激，调制峰值放电和平均（DC）的放电率被抑制在不规则型单位。抑制不规则型传入神经元也遵循视觉呈现的自然猎物，并持续很长一段时间后，猎物的刺激从视图中删除。当由生物学上显著的视觉刺激激活时，对外侧传入的抑制作用导致以下假设：在自然环境中，octavolateralis传出系统在侧线所携带的信息的外周处理中起作用。
SummaryThe activation and action of the octavolateralis efferent system was studied by chronic recordings of discharge patterns from putative efferent and single primary afferent neurons in alert, free-swimming toadfish. Efferent axons isolated in the anterior lateral line nerve showed phasic discharges following touch stimuli applied to the head or trunk and demonstrated sustained discharges to visual stimuli. Resting discharge patterns of primary afferents were categorized into irregular, burster, regular, and silent classes. Afferent discharges were often modulated by low frequency (< 1 Hz) water movement around the head generated during respiratory movements. When fish with recording electrodes implanted in the lateral line nerve were visually stimulated, modulated peak discharges and average (DC) firing rates were inhibited in irregular-type units only. Inhibition of irregular-type afferent neurons also followed visual presentation of natural prey and persisted long after prey stimuli were removed from view. The inhibitory action upon lateralis afferents when activated by biologically significant visual stimuli leads to the hypothesis that the octavolateralis efferent system functions in the peripheral processing of information carried by the lateral line in natural settings.
